Victorian Erotica Female Brass Statue

I know that there are a lot of reproductions of this type of antique but this small statue is very heavy and made from the type of high lead content brass used in the Victorian era for this type of piece. Also, considering the age of the other items that the old owner had, this statue would not have been out of place. I am nearly sure it is original and would like to find out more about it including how much it might be worth. Thank you.
